Energy Production Flashcards
Biosynthesis
Process of creating biologic compounds from smaller building blocks to support the body’s energy needs
Bioenergetics
The flow and exchange of energy within a living systemn
1st Law of thermodynamics
Energy cannot be created or destroyed, but transforms from one form to another w/o being depleted
Energy
The ability to perform work
Chemical work
Biosynthesis of molecules
Mechanical work
Muscle contraction
Transport work
Transfer of substances among cells
Second law of Thermodynamics
The tendency of potential energy to degrade to kinetic energy of motion with a lower capacity for work
Endergonic Rxn
Product has more energy than reactants
Exergonic Rxn
Product has less energy than reactants
Oxidation reaction
Transfer of oxygen atoms, hydrogen atoms, or electrons.
Reducing Agent
The substance donating or losing electrons as it oxidizes
Reduction reaction
Process which the atoms in an element gain electrons
Oxidizing Agent
The substance being reduced by gaining electrons
Oxidation-Reduction Reactions
Forms the basis for the body’s energy transfer process
